Since https://github.com/meta-llama/llama-stack/pull/2005 the run
configuration is embedded into the container image itself and the
entrypoint is correctly configured during the container image build
process. We don't need to override the container image entrypoint
anymore.

Small docs update and an update for `start-stack.sh` with missing color
and if statment logic.
# What does this PR do?
1. Makes a small change to start-stack.sh to resolve this error:
```cmd
/home/aireilly/.local/lib/python3.13/site-packages/llama_stack/distribution/start_stack.sh: line 76: [: missing ]'
```
2. Adds a missing $GREEN colour to start-stack.sh
3. Updated `docs/source/getting_started/detailed_tutorial.md` with some
small changes and corrections.
## Test Plan
Procedures described in
`docs/source/getting_started/detailed_tutorial.md` were verified on
Linux Fedora 41.
Fixes multiple issues
1. llama stack build of dependencies was breaking with incompatible
numpy / pandas when importing datasets
Moved the notebook to start a local server instead of using library as a
client. This way the setup is cleaner since its all contained and by
using `uv run --with` we can test both the server setup process too in
CI and release time.
2. The change to [1] surfaced some other issues
- running `llama stack run` was defaulting to conda env name
- provider data was not being managed properly
- Some notebook cells (telemetry for evals) were not updated with latest
changes
Fixed all the issues and update the notebook.
### Test
1. Manually run it all in local env
2. `pytest -v -s --nbval-lax docs/getting_started.ipynb`
# What does this PR do?
This commit introduces a new logging system that allows loggers to be
assigned
a category while retaining the logger name based on the file name. The
log
format includes both the logger name and the category, producing output
like:
```
INFO 2025-03-03 21:44:11,323 llama_stack.distribution.stack:103 [core]: Tool_groups: builtin::websearch served by
tavily-search
```
Key features include:
- Category-based logging: Loggers can be assigned a category (e.g.,
"core", "server") when programming. The logger can be loaded like
this: `logger = get_logger(name=__name__, category="server")`
- Environment variable control: Log levels can be configured
per-category using the
`LLAMA_STACK_LOGGING` environment variable. For example:
`LLAMA_STACK_LOGGING="server=DEBUG;core=debug"` enables DEBUG level for
the "server"
and "core" categories.
- `LLAMA_STACK_LOGGING="all=debug"` sets DEBUG level globally for all
categories and
third-party libraries.
This provides fine-grained control over logging levels while maintaining
a clean and
informative log format.
The formatter uses the rich library which provides nice colors better
stack traces like so:
```

A self-respecting server needs good observability which starts with
configurable logging. Llama Stack had little until now. This PR adds a
`logcat` facility towards that. Callsites look like:
```python
logcat.debug("inference", f"params to ollama: {params}")
```
- the first parameter is a category. there is a static list of
categories in `llama_stack/logcat.py`
- each category can be associated with a log-level which can be
configured via the `LLAMA_STACK_LOGGING` env var.
- a value `LLAMA_STACK_LOGGING=inference=debug;server=info"` does the
obvious thing. there is a special key called `all` which is an alias for
all categories
## Test Plan
Ran with `LLAMA_STACK_LOGGING="all=debug" llama stack run fireworks` and
saw the following:

Hit it with a client-sdk test case and saw this:

Sorry for the https://github.com/meta-llama/llama-stack/pull/1340 logic,
it will cause issue if in `non-container` env.

# What does this PR do?
now that llama stack supports running in venv, conda, and container
modes and the 3 scripts overlap alot, combine these three into ons
`start_stack.sh` script
## Test Plan
tested this locally on venv, conda, and container
